Golang framework extension combined with cloud native applications

Introduction to extending the Go framework with cloud-native applications includes: Extending Go frameworks, such as Gin, to create customized solutions that meet specific needs. Extending the Gin framework can use middleware or custom handlers. Integrate Kubernetes to deploy applications to the cloud and define their configuration using Helm Charts.

Go framework extensions combined with cloud native applications

Introduction
Go is a popular programming language, and its robust ecosystem of frameworks make it ideal for building cloud-native applications. By extending these frameworks, developers can create customized solutions that meet their specific needs.

Extended Gin Framework
Gin is a popular Go web framework known for its high performance and simplicity. To extend the Gin framework, you can use middleware or custom handlers.

Practical case: Add custom log middleware
Create a new middleware.go file:

package main

import (
    "context"
    "github.com/gin-gonic/gin"
    "log"
    "time"
)

func LoggerMiddleware() gin.HandlerFunc {
    return func(c *gin.Context) {
        startTime := time.Now()
        c.Next()
        endTime := time.Now()

        log.Printf("%s %s %s %d", c.Request.Method, c.Request.URL.Path, c.Request.RemoteAddr, endTime.Sub(startTime))
    }
}

func main() {
    r := gin.New()
    r.Use(LoggerMiddleware())
    // ...
}

Integrate Kubernetes
After extending the framework, applications can be deployed to the cloud using Kubernetes. You can use Helm Charts to define the deployment and configuration of your application.

Practical case: Create Helm Chart
Create a new chart folder:

mkdir chart
cd chart

Create a file named Chart.yaml Files:

apiVersion: v2
name: my-app
description: My Go application
...

Add a folder called templates containing deployment.yaml, service.yaml and any other required Kubernetes manifest file.

Conclusion
By extending the Go framework and integrating it with cloud-native platforms, developers can create custom, high-performance applications that are easy to deploy and manage.
